Description

We explore supersymmetric QFTs with eight supercharges. At superconformal fixed points, these theories typically lack a Lagrangian description, complicating their study. Recently, the magnetic quiver has been proposed as a tool to encode the Higgs branches of these theories. Utilizing this tool, our recent papers [1,2] propose a new algorithm: Decay and Fission of Magnetic Quivers, which performs Higgs branch RG-flows (Higgsings) on superconformal field theories (SCFTs). The power of the algorithm lies in its inherent simplicity, and I will show its application to SCFTs in dimensions d=3, 4, 5, and 6, including 4d Class S theories, Argyres-Douglas theories, 5d SQCD theories at UV fixed points, 6d orbi-instantons and higher-rank E-string. Furthermore, I will discuss the algorithm as a tool for studying the geometry of the Higgs branch as a symplectic singularity, demonstrating its advantages over previous algorithms, and providing evidence for the existence of a new isolated symplectic singularity.
